Abstract:
Objective This study aimed to study the effect of intra-brachial nitroglycerin administration via the angiography catheter on radial artery spasm in transradial percutaneous coronary intervention. Methods From patients undergoing transradial percutaneous coronary intervention (TRI) and succeeding in coronary angiography (CAG), 810 patients who needed percutaneous coronary intervention (PCI) (including Percutaneous Transluminal Coronary Angioplasty and/or stent implantation) were erolled, including 413 patients in the study group and 397 patients in the control group. When coronary angiography completed, positioned the angiography catheter over brachial artery and patients in the group received an administration of 400μg nitroglycerin via the angiography catheter. The control group received an administration of 400μg nitroglycerin via the sheath. The incidence of RAS were recored and compared. Resultes Baseline characteristics were similar between two groups. In the study group, the incidence of RAS was signiifcatively lower (18 vs. 33, P=0.021). Conclusions Intra-brachial nitroglycerin administration via the angiography catheter can prevent RAS during the insertion of guiding catheter in TRI.
